What temperature range causes deformation in polypropylene outdoor bar stools?

Polypropylene outdoor bar stools are popular for their durability and affordability, but they can deform under extreme temperatures. Typically, polypropylene begins to soften and lose structural integrity at temperatures above 140°F (60°C), while prolonged exposure to freezing conditions below 32°F (0°C) may make it brittle. For optimal performance, avoid placing these stools in direct sunlight during peak summer heat or in unheated outdoor spaces during winter. Choosing high-quality, UV-stabilized polypropylene can improve resistance to temperature-related deformation. Proper care and storage during extreme weather will extend the lifespan of your outdoor furniture.
